Lin Shen watched for a while and discerned the anomaly.
From the mountain cave behind the Asura Ghost King, black smoke continually billowed outwards. This cold, sinister smoke, mostly drifted towards the Asura Ghost King's body, accumulating around him as though granting him a significant boost.
A portion of the black smoke clung to the bottom of the valley, making the nearby area resemble a sea of black clouds.
The Asura Ghost King battled amidst this smoke, while the Nirvana Beings and their pets all fought him from the air, daring not to touch the black smoke.
Bing Leiya explained, "This black smoke is extremely Yin and cold. Even the bodies of Nirvana Beings, upon contact with the black smoke, can be invaded by the cold. At the lightest, one's body will be frozen stiff; at worst, the blood will coagulate into ice. Those with inferior physique and Power of Nirvana simply cannot survive in the smoke, let alone fight."
